Frequently Asked Questions
Quick answers to common questions
Which SQL dialects are supported?+
Standard SQL, MySQL, PostgreSQL, SQLite, BigQuery, Spark SQL, and Transact-SQL. Pick the dialect that matches your database for best formatting results.
Does this validate SQL syntax?+
The formatter parses SQL to apply layout rules. Severely invalid syntax may show a format error, but passing formatting does not guarantee the query will run on your database.
How do keyword case options work?+
Choose UPPERCASE, lowercase, or preserve to control how reserved words like SELECT and WHERE appear in the formatted output.
What does break before AND/OR do?+
When enabled, boolean operators start on a new line before the condition, which is a common readability style for complex WHERE clauses.
Is my SQL sent to a server?+
No. Formatting runs entirely in your browser using the sql-formatter library with no network requests.
